As from January 1st 1972 the municipalities
Bockhorn, Eschlbach, Grünbach and Salmannskirchen have
been joined to form the new municipality Bockhorn. Of these municipalities Bockhorn and Grünbach used their own arms, that have become
obsolete by the merger. For the design of the arms of the new
municipality Bockhorn parts of these both obsolete arms have been
referred to. The incorporation of parts of the former
municipality Matzbach on May 1st 1978 (see also Lengdorf) did not lead to an alteration of the arms.

Granting of the arms by the Bavarian
Ministry of the Interior on January 5th 1950.
